In One Piece, there are characters who will laugh in a strange pattern, sometimes the laughter will sound different or when there are different words in "haha". Their laughters are very unique and can be based on their personalities or appearances. Here is the list of characters who laugh in different ways. It should be noted that Robin and Hancock's laughing style of "Fufufufufu" is a common Japanese laughing style used for mature women in anime and manga. In additon, the common phrase "Ara, ara, ara" is not a laugh, but rather the Japanese version of "Oh my, oh my, oh my".
